• Low input and output leakage ≤ 1µA (max.)
DESCRIPTION:
The FCT162344AT/CT/ET is a 1:4 address line driver built
using advanced dual metal CMOS technology. This high-
speed, low power device provides the ability to fanout to
memory arrays. Eight banks, each with a fanout of 4, and 3-
state control provide efficient address distribution. One or
more banks may be used for clock distribution.
The FCT162344AT/CT/ET has balanced output drive with
current limiting resistors. This offers low ground bounce,
minimal undershoot and controlled output fall times reducing
the need for external series terminating resistors.
A large number of power and ground pins and TTL output
swings also ensure reduced noise levels. All inputs are
designed with hysteresis for improved noise margins.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
NCP = Number of Clock Inputs at fCP
fi = Input Frequency
Ni = Number of Inputs at fi
